Hirsiset launched a dovetail corner model in year 2005. Dovetail corner enables to build Hirsiset loghouse without the cross joint corner. Dovetail corners may be used in areas where cross joint corners are not allowed, like several towns in Finland.

Hirsiset has manufactured dove tail corners already 10 years, since 2005. Now the corner is even more better due the new milling cutters which gives better working quality.
